I am using STM32MP157C and as part of the project i am trying to configure the hardware by enabling and disabling certain security features(tamper detection,trust zones,rd and wr protection etc)
I would like to know if there is a way to access the system registers for these features and write to them using the A7 in the Stm32.

You may look at busybox devmem tool which is a nice wrapper to /dev/mem access.
